Congenital teeth which are present at birth are referred to as natal teeth, while those that erupt during the first month of life are referred to as neonatal teeth. There have been many reports on the frequency, classification, causes and treatments of early eruption. We encountered two cases of congenital teeth which required extraction right after birth.
Congenital teeth are rare, and almost always involve milk teeth, which was the case in the present two cases as well.
The congenital teeth in the present cases showed marked mobility, and because spontaneous loss was expected, it was decided to extract the teeth to prevent aspiration.
After adequately explaining the risks of misalignment and malocclusion associated with extraction of the congenital teeth to the patients' mothers, we plan to continue long-term follow-up.
